In my never ending search for speed I am today trying to move upward of 5.2ghz on my i7 2600K.
Sadly, I keep being met with either BSOD 101 or 124.Settings as follows and working fine for 5.2ghz.
- Intel Core i7 2600K
- Asus Maximus IV Extreme-Z
- Samsung 30nm DDR3 running at 2133 9-10-9-27-1T (But dropped back to 1600 for these tests)
- 3x sapphire 7970HD running at 1200/1600
- Psu: 1250w
- Cooling = huge loop with 2 rads, 1 external 1260, temps are not a problem.
I today tried multiple overclocking profiles, but in general it goes like :
- CPU Level Up : Auto
- Ai Overclock Tuner : Manual
- BCLK/PCIE Frq : 100
- Multiplyer: 53
- Turbo Ratio : Auto
- Memory Freq : DDR3-1600Mhz
- Manual Dram Timings : 10-10-10-30-1T
- Dram voltage 1.5v (this is 1.3v ram, I use 1.5v at 2133 so know its stable there)
Digi VRM :
- PWM Mode : Extreme
- Load-line Calibration : 75%-100%
- Switching Freq - Manual : 350
- Phase Control : Extreme
- Over-Current Prot : 140%
- Over Temp Prot : disabled
VDRAM, CCSA, VCCIO :
- VCCIO 1.1v
- CPU PLL 1.75 - 1.85 tried (normally run 1.75)
- Full Phase Control : Auto
- Over-Current Prot : Disabled
CPU Voltage : Offset
Currently stabilises at 5.3ghz with 1.552 volts but in heaven it drops a 101 or 124 error after about 20 stages.
Ideally I would like to get a stable 5.4Ghz overclock if possible. So, unless I have missed something obvious, I may now need to start learning about things I know little about, having never had to play with them. Things such as C states and Skew. Also, i know my offset between VCCIO and Dram volts has exceeded 0.5v so will try tweaking that tonight. Anyone know what happens when its wrong?
This isnt for a 24/7 stable overclock, its used for benching only. 24/7 I runa beautifully setup and stabilised 4.7ghz with 1.41volts vcore. I also accept that the chip simply may not do it... end of.
